Bitsery is a header-only C++ binary serialization library designed for real-time networking, especially in games. It produces compact, metadata-free output with compile-time cross-platform guarantees and extensible bit-level control.

Use cases

• serialize game state for real-time network delivery
• compact binary serialization of C++ structs
• cross-platform binary data exchange without IDL or code generation
• fast serialization benchmarked against cereal, protobuf, msgpack
• bit-level serialization control for bandwidth-constrained protocols
• serialize to files, streams, or buffers with runtime error checking

When to choose

• you need the smallest possible serialized data size with no metadata overhead
• you want a header-only C++11/14 library with no macros or code generation
• you are building real-time multiplayer games or network protocols
• serialization speed and deserialization speed are critical

When to avoid

• you need schema evolution with self-describing formats like protobuf or flatbuffers
• you want language interoperability beyond C++ out of the box
• you prefer reflection-based or code-generated serialization workflows
